MACHINE FOR SCOURING AND POLlSHlNG STONE.

SPECIFICATION forming part of Letters Patent No. 314,905, dated March 31, 1885.

Application filed September 3, 1884. (No model.) v

To all whom, it may concern:

Be it known that I, HUGH YOUNG, of the city and county of New York, in the State of New York, have invented a new and useful Improvement in Machinery for Scouring and Polishing Stone, of which the following is a specification.

My invention relates to machinery for scouring and polishing stone in which there is used, in combination with a rotary rubbing-bed, a crane for handling the stone to be scoured or polished on said bed.

One object of the said invention is to obtain great stability for the upper bearings of the upright rubbing-bed shaft and of the crane, and to maintain positively the proper relation between them, and another object is, while so maintaining the relation between the said bearings, to provide for the swinging of the arm of the crane under the gear provided on the said shaft for receiving its rotary motion. i

In the accompanying drawings, Figure 1 is a plan of a rubbing-bed, a crane, and a framework embodying my invention; and Fig. 2 is a sectional elevation thereof on the dotted line as m, Fig. 1.

Similar letters of reference designate corresponding parts in both figures.

A designates the rubbing-bed or revolving table, which is supported and carried by an upright shaft or spindle, B. The lower end of the shaft or spindle B is supported in a step-bearing, a, and near its upper end it carries a bevel-wheel, B, which receives motion from a similar'wheel or pinion, G, on a horizontal shaft, 0. The shaft 0 may be driven by belt-gearin g or otherwise, in the usual way.

At the upper end of the shaft or spindle B is constructed a horizontal framework, which consists, essentially, of longitudinal pieces or timbers D D D, cross pieces or timbers D D D, and diagonal pieces or timbers D D all securely bolted or otherwise secured together. The diagonal pieces or timbers D converge toward one side of the horizontal frame, as shown in Fig. 1, and at their meeting ends are connected by a bracket or casting, b, which forms the upper bearing for the crane-post E, the lower end of said post being supported in a step-bearing, c. I

E designates the horizontally-extending swinging arm of the crane, and d designates a carriage adapted to travel on the said arm,

and from which the tackle 6 depends.

F designates a stone suspended or held by the tackle c and placed on the bed A, and E designates the mechanism whereby the raising and lowering of the stone may be effected, and which may be of any suitable character. The horizontal framework also comprises short cross pieces or timbers D which connect the two longitudinal pieces or timbers D D, which areover the bed A. The bearingf for the upper end of the shaft or spindle B is secured to the intermediate cross piece or timber D, and the horizontal shaft C is mounted in bearings g, which are secured to the timbers D D D as best shown in Fig. 1.

Inasmuch as the horizontal framework, constructed as described, supports the bearingf 7c for the upper end of the shaft or spindle B, the bearing 1) for the upper end of the cranepost E, and the bearings g for the horizontal shaft U, it will be readily seen that all these hearings, the two shafts, and the crane-post are held in their proper relative positions, and are prevented from moving relatively to eac other.

It will be seen in Fig. 2 that the gearing B G and the horizontal frame-work D D D D are all above and higher than the swinging arm E of the crane, and that the arm may swing close to the upright shaft or spindle B; hence there will be nothing in the way of the depending tackle e, and the stone F can be placed on the bed A as close to the shaft or spindle B as is desired.

The horizontal frame-work D D D D is preferably supported by triangular legs or frames, which are formed by upright post-s G, and inclined braces H, extending from the tops of the posts downward and away from the posts. As many of'these legs or frames may be employed as is necessary, and they are so arranged as to brace the upper horizontal frame in directions both lengthwise and crosswise thereof.

By making the upper horizontal frame-work above described of large size or area I am enabled to arrange the posts G of the triangular legs so that they will not interfere with the swinging of the arm E of the crane in the direction indicated by the dotted are shown in Fig. 1. The lower end of the posts G and 5 the diagonal braces H are provided with suitable anchors, G H, whereby they are prevented from sinking into the ground and from being drawn out of the ground. They are thus adapted to resist both crushing and 10 tensile strain.

WVhat I claim as my invention, and desire to secure by Letters Patent, is-

l. The combination, with a rubbing-bed and its upright shaft and a crane, of a hori- I5 zontal frame-work supporting both the upper
